I got an abortion on March 14th of this year, i bled right after for about 3 weeks, on April 1st i had unprotected sex, he said he didnt cum inside me, but he did precum inside. Last week i took a pregnancy test and it was positive, and about 2 days ago i took another one and its negative, today, my discharge is clear with brown specks in it. Should i take a pregnancy test?
